NON- SLIPPING ATTACHMENT FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patentv N0. 780,807, dated January 24, 1905.

Application filed September 6.1904. Serial No. 223,520. i

tachments, and more particularly to an attach- 5 ment for the sole of the boot or shoe designed to prevent slipping when Walking upon ice or slippery pavements and the like; and my in vention consists of certain novel features of combination and construction of parts, the preferred form whereof will be hereinafter set forth, and pointed out in the'claim.

The prime object of my invention, among others, is to provide an attachment of the character specified which will be found reliably efficient and which may be readily applied to use and disengaged from the boot or shoe when further use is not required thereof.

A further object of my invention is to provide an attachment designed to meet the requirements above specified and which will prove flexible in character and will therefore readily conform to all the movements of the foot incident to wearing the same.

Another object is to prevent undue strain being placed upon the sole of the foot and also to enable the attachment to be readily taken oil? and sharpened if deemed desirable.

Other objects and advantages will be hereinaftermade clearly apparent, reference being had to the accompanying drawings, which are made a part of this application, and in which Figure 1 shows a side elevation of my invention complete as applied to use. Fig. 2 is a bottom plan view of my invention as applied to use upon a shoe or boot 0f the usual or any preferred constructiomwhile Fig. 3 shows a longitudinal central section of a shoe with my attachment applied thereon.

For convenience of reference to the various details of my invention and cooperating acsame numeral applying to a similar throughout the several views.-

cessories numerals will be. employed, the part Referring to the numerals on the drawings, 1 designates a shoe of the usual or any preferredconstruction, the same being designed to be representative of boots and shoes in general to which my ice-creeping attachment is secured by means of the ankle-strap 2-, supple- .mented by the toe-strap 3 or the equivalent thereof. The heel member 4 is provided with a flange 5 to fit around or receive the heel of the boot or shoe, said flange having openings or slots 6, in which are anchored the ankle-straps 2, said straps beingprovided with a disengaging buckle or clamp-like member 7 or the equivalent thereof. The heel-member 4 is formed upon its forward side with a preferably integral extension 8, to the end of which is attached or may be integrally formed'thereon the crossbar 9 of a width to reach across the sole of the shoe or boot. I have also provided a toe-plate l0 and intermediate bars or plates 11, 12, 13, and 14, it being understood that any desired number of said bars may be employed, as will be obviously necessary to cover the entire sole of the shoe or boot, the said bars being flexibly connected together by means of the coiled wires orspringlike members 15. The springlike members 15 may be connected at intervals throughout their entire length with said crossbars, whereby said bars will all be joined together and the last spring member joined to the bar .9 and the toe-plate 10; but in the present instance 1 have shown said spring members attached only at their ends, as designated by the numeral 16, the end of the wire being interlaced through the aperture 16, provided in the contiguous edge of the bars or the toe- I plate 10, as will be obvious. members 15 will thus impart a high degree of flexibility to the entire attachment, it being understood that each of the cross-bars mentioned, as well as the heel and toe plate, are

The spring-like from slipping in any direction, and thereby atfordlng a secure footing to the person wearing my attachment.

It will be understood that the spring members 15 are connected to the several cross-bars and the toe-plate in such a manner that the tension of the spring will hold the toe-plate firmly in place, and therefore prevent it from hanging down and coming in the way.

The entire attachment may be quickly removed from the shoe or boot, as by disengaging the buckles 7 and 18 or other equivalent fastening.

Obviously the various parts of my invention, excepting the spring-like members 15, may be readily fashioned from suitable sheet metal, the friction-points 17 being also formed at the same operation, and while I have de scribed the preferred combination and construction of parts I desire to comprehend in this application all substantial equivalents and substitutes that may be considered as falling fairly within the scope and purview of my invention.

Having thus fully described myinve-ntion,

what I claim as new, and desire to secure ,by Letters Patent, is

The herein-described ice-creeper or nonslipping attachment for boots and shoes, comprising a heel member shaped to lit the heel and provided with frictional points to take into the ice, sleet and the like, said heel member having a forward extension 8 provided with a cross-bar 9; a toe-plate and a plurality of flexibly-united cross-bars joining the 111(311'1- JOHN MCGRA'ITH.
